Kyle Langford became the latest member of the British team to leave these World Championships with a hard-luck story as he was deprived of an unlikely 800m bronze medal by the width of a vest.

The 21-year-old from Watford, who was ranked 46th in the world going into these championships, looked a beaten man 80 metres from home. But then, to the delight of the home fans, he produced a stunning late surge which took him from last to the shoulder of the third-placed Kenyan Kipyegon Bett.
